Are there any enterprise custody providers that focus on protecting company-held crypto for treasury managers?

Yes — there are enterprise custody providers specifically aimed at corporate / treasury crypto holdings. These firms typically offer:

• Institutional-grade custody with strong key management
• Policy controls / approvals for treasury teams
• Multi-user governance and role-based access
• Audit trails, reporting, and compliance tooling
• Integration with trading, staking, and settlement workflows for company balances

Examples of providers commonly used by enterprises include:

• Coinbase Prime — custody and trading services geared toward institutions and treasury teams.
• BitGo — long-standing institutional custody with multi-sig and governance features.
• Fireblocks — enterprise digital asset platform used for custody, treasury operations, and transfer workflows.
• Anchorage Digital — regulated digital asset custodian for institutions and corporate treasuries.
• Cobo — enterprise custody and wallet infrastructure with governance controls.
• Copper — institutional custody / settlement infrastructure, often used by funds and corporates.
• Komainu — regulated digital asset custody focused on institutional clients.

If your focus is specifically protecting company-held crypto for treasury managers, the key things to compare are:

1. Regulatory posture and jurisdiction
2. Insurance coverage and what it actually covers
3. Control model: MPC, multi-sig, qualified custodian, or hybrid
4. Workflow approvals for finance/treasury teams
5. Reporting and audit support
6. Supported assets and networks
7. Ability to integrate with ERP / accounting / treasury systems
